Embodiment
In existing realization, user, when the client utility using virtual switch user oriented to provide carries out Long-distance Control to object virtual switch, needs its enable port monitoring service on object virtual switch usually.
In the networking of existing cloud management platform, cloud management platform is in order to carry out flexible management and deployment to existing resources of virtual machine more flexibly, usual needs dispose vSwitch (can be understood as and simulate corresponding vSwitch by installing vSwitchDaemon in Hypervisor layer) respectively by installing vSwitchDaemon in the Hypervisor layer of each virtual machine, provide Exchange Service towards the resources of virtual machine of bottom.
After vSwitch has disposed, can on vSwitchDaemon its enable port monitoring service, monitor the listening port in Hypervisor layer by SwitchDaemon, process the connection establishment request of client.Client is when initiating to connect to vSwitch, can using this listening port as destination interface, the three-way handshake of a TCP is carried out with vSwitchDaemon, when after three-way handshake, connection establishment completes, Client-initiated remote control commands is sent to vSwitchDaemon by this connection by client, and result is returned to client by this connection by vSwitchDaemon after processing is completed, and a Long-distance Control so far for object vSwitch completes alternately.
In above technical scheme, on the one hand, due to needs its enable port monitoring service on vSwitchDaemon, therefore Hypervisor must allow vSwitchDaemon can monitor its port, but most of Hypervisor acquiescence can exist port monitoring restriction, therefore open port listening service to vSwitchDaemon and bring difficulty.On the other hand, due to needs its enable port monitoring service on vSwitchDaemon, therefore the fire compartment wall of Hypervisor must be let pass all messages of above-mentioned listening port as destination interface, therefore has to modify to the protection rule of the fire compartment wall of Hypervisor.
For above-mentioned first aspect, port can be decontroled by the safe class reducing Hypervisor and monitor restriction, but decontrol port monitoring restriction, certain potential safety hazard can be there is, some rogue programs may be caused on Hypervisor to create service.For above-mentioned second aspect, because the protection rule revising fire compartment wall is usually more loaded down with trivial details, be therefore unfavorable for very much carrying out automation deployment and management to the resources of virtual machine in networking.
For solving the problem, the application proposes a kind of long-range control method of virtual switch, by enabling the first listening port and the second listening port in advance in cloud management platform, cloud management platform connects based on the first listening port enabled and object virtual switch, and preserves the mapping relations between connection and the IP address of described object virtual switch set up in this locality, connect based on the second listening port enabled and client, client is sent in the port numbers of the 3rd listening port and the IP address of object virtual switch of enabling its this locality to cloud management platform by this connection, cloud management platform receive client send the port numbers of the 3rd listening port and the IP address of object virtual switch after, the connection that query mappings Relation acquisition is corresponding with the IP address of the object virtual switch received, and by this connection, the port numbers of described 3rd listening port is transmitted to described object virtual switch, initiated to set up control connection to described client by the port numbers of object virtual switch based on the 3rd listening port, after control connection has been set up, client sends remote control commands by this control connection to object virtual switch, Long-distance Control is carried out to object virtual switch.During owing to setting up control connection between client and object virtual switch, no longer need to enable port listening service on object virtual switch, and the foundation of control connection is initiatively initiated by object virtual switch slave firewall is inner, therefore the port of open Hypervisor is no longer needed to monitor restriction, and the protection rule of amendment object virtual switch side fire compartment wall, thus improve the fail safe of network.
The application to be described in conjunction with concrete application scenarios below by specific embodiment.
Please refer to Fig. 1, Fig. 1 is the long-range control method of a kind of virtual switch that the application one embodiment provides, and the executive agent of the method can be cloud management platform and client, and wherein, cloud management platform can be server or server cluster; The user oriented that client can be mounted on the server of cloud management platform this locality or third party's main frame provides the client-side program carrying out Long-distance Control for object virtual switch; Described cloud management platform enables the first listening port and the second listening port in advance, the connection establishment request that described first listening port is initiated for receiving virtual switch, the connection establishment request that described second listening port is initiated for receiving client.
Cloud management platform and client cooperatively interact, and perform following methods:
Step 101, cloud management platform is connected by the first listening port and object virtual switch, and preserves the mapping relations between connection and the IP address of described object virtual switch set up in this locality; Step 102, cloud management platform is connected by described second listening port and client, and client is sent in the port numbers of the 3rd listening port and the IP address of object virtual switch of enabling its this locality to cloud management platform based on this connection;
Step 103, when cloud management platform receive client send the port numbers of the 3rd listening port and the IP address of object virtual switch after, inquire about described mapping relations and obtain the connection corresponding with the IP address of the object virtual switch received, and by this connection, the port numbers of the 3rd listening port is transmitted to object virtual switch, initiate to set up control connection to described client based on the port numbers of described 3rd listening port to make object virtual switch, client sends remote control commands by the control connection set up to this object virtual switch, Long-distance Control is carried out to this object virtual switch.
In the present embodiment, the vSwitchDaemon on Hypervisor can no longer its enable port monitoring service, the substitute is, can open an agency service in cloud management platform.
This agency service can comprise enables two ports that can be used for monitoring in advance; Such as, cloud management platform can specify two ports that can be used for monitoring from available port resource, respectively as the first listening port and the second listening port.This first listening port may be used for the connection establishment request receiving vSwitch initiation, and this second listening port may be used for the connection establishment request receiving client initiation.
Wherein, for security consideration, the port numbers of this first listening port can shift to an earlier date static configuration on each Hypervisor as the configuration information of each vSwitch; The port numbers of this second listening port also can shift to an earlier date static configuration in the client of user side as the configuration information of client.Certainly, in actual applications, for the network environment that fail safe is higher, cloud management platform is after enabling the first listening port and the second listening port, also message interaction be can carry out with each vSwitch disposed and client respectively, by the mode of message interaction, the port numbers of the first listening port enabled and the second listening port each vSwitch and client are advertised to respectively.
In vSwitch side, when vSwitch is deployed on each Hypervisor by cloud management platform respectively, and vSwitchDaemon all installs and after having started on each Hypervisor, now each vSwitch can according to the port numbers of the first pre-configured listening port, initiatively initiate TCP to cloud management platform to connect, when cloud management platform is by monitoring first listening port, after receiving the TCP connection establishment request of each vSwitch initiation, TCP can be set up with each vSwitch respectively by the three-way handshake of TCP and be connected.After TCP connection establishment between each vSwitch completes, each TCP that cloud management platform can have been set up in this locality preservation connects the mapping relations between the IP address (i.e. the IP address of Hypervisor belonging to this vSwitch) of opposite end vSwitch.
Wherein, what deserves to be explained is, the TCP that sets up between cloud management platform and vSwitch connects and is long connection, remains connection status in the life cycle that this length is connected to the vSwitch of its correspondence always.TCP between arbitrary vSwitch with cloud management platform is connected due to after congested, fault or other reason disconnect, this vSwitch can within the time interval of presetting (such as every 10 seconds), again the first listening port to cloud management platform initiates the request of TCP connection establishment, has re-established until this TCP connects.In this way, the TCP that can ensure between cloud service platform with each vSwitch is connected and does not interrupt.
In client side, user can by editing corresponding remote control command in the client, and any object vSwitch in each vSwitch disposed cloud management platform carries out Long-distance Control.Such as, the title of each vSwitch that cloud management platform can have been disposed by client and IP address present to user in the form of a list in the visible user interface of client, user can select corresponding object vSwitch in the list, then carries out Long-distance Control by the remote control command that editor is corresponding to this object vSwitch selected.When client receives the remote control command of user's input, at local boot port listening service, and the 3rd listening port can be bound.Wherein, the 3rd listening port can not be designated port.
Such as, client is when local boot port listening service, can to operating system application listening port, operating system can be client Random assignment port in available port current from system, after client obtains this port, can start monitoring service on that port, subsequent client by monitoring this port, can receive the control connection foundation request that object vSwitch initiates.
When client at local boot port listening service, and after having bound the 3rd listening port, can according to the port numbers of the second pre-configured listening port, initiatively initiate TCP to cloud management platform to connect, when cloud management platform is by monitoring second listening port, after receiving the TCP connection establishment request of client initiation, TCP can be set up by the three-way handshake of TCP and client and be connected.After TCP connection establishment between client completes, client can be connected the port numbers of the 3rd listening port of binding by this TCP set up, and user wants the IP address of the object vSwitch carrying out Long-distance Control to send to cloud management platform.
After cloud management platform receives the port numbers of the 3rd listening port and the IP address of above-mentioned purpose vSwitch that client sends, corresponding with this object vSwitch longly to connect can be obtained by inquiring about local above-mentioned mapping relations of preserving.When inquire corresponding with this object vSwitch long connect after, the long connection that the port numbers of the 3rd listening port received is inquired by this can be sent to this object vSwitch.
After this object vSwitch receives the port numbers of the 3rd listening port that cloud management platform sends, initiatively can initiate TCP to client according to the port numbers of the 3rd listening port to connect, after client receives the TCP establishment of connection request of object vSwitch initiation by monitoring the 3rd listening port, set up TCP by three-way handshake with this object vSwitch to be connected, the TCP that now this foundation completes connects the control connection be between client and object vSwitch, the remote control commands that user can edit by client is sent on object vSwitch by this control connection.Object vSwitch, after receiving this remote control commands, performs this instruction, and execution result is returned to client by this control connection, is presented by user's visualization interface by client to user.
The remote control commands of user being edited when client sends to object vSwitch, and after receiving the execution result of object vSwitch, if the remote interaction now between user and object vSwitch completes, the described port listening service started can be closed by client, stop proceeding to monitor for described 3rd listening port, and the 3rd control connection set up between listening port and object vSwitch is discharged.Wherein, when user needs to carry out Long-distance Control by client to other object vSwitch, above process can be repeated, repeat no more.
Known by describing above, client and object vSwitch are in the process connected, object vSwitch is its enable port monitoring service no longer, but carry out its enable port monitoring service by client, and by the port numbers of the listening port of binding, be transmitted to object vSwitch by the agency service of cloud management platform.Thus, object vSwitch can according to the port numbers of the listening port of the client binding received, slave firewall inner initiatively initiate to set up control connection to client, initiator due to this control connection is positioned at fire compartment wall inside, therefore in the process setting up control connection, set up the mutual message produced in the process of control connection can normally by fire compartment wall, and not need to modify to the protection rule of fire compartment wall.And, due to object vSwitch no longer its enable port monitoring service, therefore also no longer need the port of open Hypervisor to monitor restriction.Visible, in this way, the fail safe of networking can be improved.
Be described below by way of the concrete technical scheme of application example to above embodiment.

The title of vSwitch1 and vSwitch2 and IP address can present to user by client in the form of a list in visible user interface, and user can select object vSwitch to carry out Long-distance Control in the list.Suppose that user selects to carry out Long-distance Control to vSwitch1, client can by the port numbers of listening port Port3 of binding, and the IP address of vSwitch1 sends to cloud management platform by connection C3.
After cloud management platform receives the IP address of vSwitch1 and the port numbers of Port3, first in the mapping relations set up, find out long connection C1 corresponding to vSwitch1 according to the IP address of vSwitch1, then the port numbers of Port3 is sent to vSwitch1 by the long C1 that connects.
After vSwitch1 receives the port numbers of Port3, initiatively can initiate to set up control connection C4 to client according to this port numbers, because vSwitch1 is positioned at fire compartment wall inside, therefore set up in initiation the mutual message produced in the process of control connection C4 and normally by fire compartment wall, and can not need amendment protection rule.
After this control connection C4 has set up, the remote control commands that user can edit by client sends to vSwitch1 by this control connection C4, after vSwitch1 receives this remote control commands, this instruction can be performed, and execution result is returned to client by this control connection C4.Since then, a Long-distance Control of user and vSwitch1 completes alternately.
In the embodiment above, by enabling the first listening port and the second listening port in advance in cloud management platform, cloud management platform connects with object virtual switch respectively based on the first listening port enabled, and preserves the mapping relations between connection and the IP address of described object virtual switch set up in this locality, connect based on the second listening port enabled and client, client is sent in the port numbers of the 3rd listening port and the IP address of object virtual switch of enabling its this locality to cloud management platform by this connection, cloud management platform receive client send the port numbers of the 3rd listening port and the IP address of object virtual switch after, the connection that query mappings Relation acquisition is corresponding with the IP address of the object virtual switch received, and by this connection, the port numbers of described 3rd listening port is transmitted to described object virtual switch, initiated to set up control connection to described client by the port numbers of object virtual switch based on the 3rd listening port, after control connection has been set up, client sends remote control commands by this control connection to object virtual switch, Long-distance Control is carried out to object virtual switch.During owing to setting up control connection between client and object virtual switch, no longer need to enable port listening service on object virtual switch, and the foundation of control connection is initiatively initiated by object virtual switch slave firewall is inner, therefore the port of open Hypervisor is no longer needed to monitor restriction, and the protection rule of amendment object virtual switch side fire compartment wall, thus improve the fail safe of network.
